摘要
本文引入虚拟同步发电机技术,针对有功频率控制、电压无功控制以及电压电流控制分别进行优化。并通过小信号模型分析阻尼系数对岸电系统输出的影响,进而制定了船舶岸电电源自适应阻尼控制策略。最后,在PSCAD/EMTDC中进行仿真对比验证,仿真结果验证了船舶岸电电源自适应阻尼控制策略的有效性。
Virtual synchronous generator technology is introduced to optimize the control of active frequency, voltage reactive power, voltage and current respectively. A small signal model is used to analyze the impact of damping coefficient on the output of shore power system, and then the strategy of self-adaptive control with damping is established for ships’ shore power source. Finally, PSCAD/EMTDC is used for the simulation, comparison and verification of the above strategy, which shows its effectiveness.
